Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides a test chamber with an air drying function, such as Figure 1-5 As shown, the test chamber with air drying function includes an outer chamber 1, a sealing cover 2 rotatably installed on the upper end of the outer chamber 1, an operation panel 3 at the upper end of the outer chamber 1, an insulated inner liner 4 fixedly installed inside the left end of the outer chamber 1, a latch 6 at the front of the upper end of the outer chamber 1, a circulating fan 7 fixedly installed inside the left end of the outer chamber 1, an electric heater 8 installed inside the left end of the outer chamber 1, the electric heater 8 being fixedly connected to the circulating fan 7, and a drying component installed inside the lower end of the outer chamber 1, the drying component being connected to the electric heater 8.

[0017] In use, inputting commands through the operation panel 3 activates the electric heater 8 and the circulating fan 7, drawing in and heating outside air. The air is then dried by the drying assembly, and the dried air is blown into the insulated inner liner 4, providing a dry and stable testing environment for the test samples placed on the sample rack 5.

[0018] The heat-insulating inner liner 4 is equipped with a sample placement rack 5, which is made of stainless steel mesh.

[0019] The sample rack 5 is designed to facilitate the placement of test samples. The stainless steel mesh design improves the structural strength of the sample rack 5 and also facilitates ventilation and drying of the test samples after placement.

[0020] Multiple sets of leveling feet 14 are fixedly installed at the lower end of the outer casing 1 of the test chamber, and the multiple sets of leveling feet 14 are in contact with the ground.

[0021] During use, the leveling feet 14 allow the outer casing 1 of the test chamber to be placed stably by adjusting the leveling feet 14 according to the unevenness of the ground it is placed on, thus preventing tilting and improving the stability of the test chamber during use.

[0022] The drying assembly includes a dehumidification chamber 9, which is located inside the lower end of the outer chamber 1 of the test chamber. The left side of the dehumidification chamber 9 is connected to the electric heater 8 through a pipe. A refrigeration dehumidification evaporator 10 is fixedly installed inside the dehumidification chamber 9. A dehumidification compressor 12 is fixedly installed on the rear side of the lower end of the outer chamber 1 of the test chamber. The dehumidification compressor 12 is connected to the dehumidification chamber 9 through a pipe. A cooling fan 13 is fixedly installed on the rear side of the dehumidification compressor 12. An adsorption dryer 15 is installed inside the right end of the outer chamber 1 of the test chamber. The adsorption dryer 15 is connected to the dehumidification chamber 9 through a pipe. The adsorption dryer 15 is also connected to the heat-insulating inner liner 4 through a pipe.

[0023] The refrigeration dehumidifier 10 condenses the moisture in the air to achieve preliminary dehumidification. The dehumidifier compressor 12 provides cooling power to the refrigeration dehumidifier 10, and heat transfer is achieved through refrigerant circulation. At the same time, the cooling fan 13 forces heat dissipation, which liquefies and circulates the refrigerant, preventing the dehumidifier compressor 12 from generating high temperatures due to prolonged operation, which would affect the dehumidification effect. Finally, the air enters the adsorption dryer 15, where the residual moisture in the air is adsorbed to ensure the dryness of the air. The treated dry air is blown into the insulated inner liner 4 through pipes, providing a dry and stable test environment for the test samples.

[0024] A collection box 11 is movably inserted into the lower end of the dehumidification chamber 9, and the collection box 11 is arranged parallel to the refrigeration dehumidification evaporator 10.

[0025] The collection box 11 facilitates the collection of moisture condensed on the evaporator 10, preventing moisture residue in the dehumidification chamber 9 and thus improving the dehumidification efficiency of the dehumidification components. When the moisture in the collection box 11 accumulates to a certain level, the operator can open the dehumidification chamber 9, remove the collection box 11, and empty the moisture. The operation is simple and convenient, improving the practicality of the test chamber.

[0026] An air filter is installed between the circulating fan 7 and the electric heater 8.

[0027] The air filter can filter the intake air, effectively removing dust and impurities from the air, preventing dust and impurities from contaminating the test samples. It can also protect the normal operation of the electric heater 8 and the circulating fan 7, and extend their service life.

[0028] Working Principle: During operation, the operator first opens the sealing cover 2, places the sample to be tested on the sample rack 5, then closes the sealing cover 2 and locks it with the latch 6 to ensure the airtightness of the outer chamber 1 and the insulated inner liner 4. Next, the operator inputs the required test commands through the control panel 3, starting the electric heater 8 and the circulating fan 7. The circulating fan 7 begins working, drawing outside air into the outer chamber 1 of the test chamber, where it is filtered through an air filter to remove dust and impurities. The filtered air then enters the electric heater 8 for heating, increasing its temperature. The heated air then enters the dehumidification chamber 9, where it exchanges heat with the refrigeration dehumidification evaporator 10. Moisture in the air condenses into liquid water on the refrigeration dehumidification evaporator 10, achieving preliminary dehumidification. The condensed water drips into the collection box 11 for collection. The pre-dehumidified air then enters the dehumidification compressor 12 for further dehumidification. The dehumidifier compressor 12 provides cooling power to the refrigeration dehumidifier evaporator 10, and heat transfer is achieved through refrigerant circulation. At the same time, the cooling fan 13 starts to work, forcibly dissipating heat from the dehumidifier compressor 12 to prevent it from generating high temperatures due to prolonged operation, which would affect the dehumidification effect. The air processed by the dehumidifier compressor 12 enters the adsorption dryer 15, where residual moisture in the air is adsorbed to ensure the dryness of the air. The processed dry air is blown into the insulated inner liner 4 through a pipe, providing a dry and stable test environment for the test samples placed on the sample rack 5. During the test, the operator can monitor the temperature and humidity parameters inside the test chamber in real time through the control panel 3 to ensure the accuracy and stability of the test. After the test, the operator can open the sealing cover 2, take out the test samples for observation and analysis, and regularly empty the water in the collection box 11.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
